“…In one of the few studies carried out with the pomegranate cutting propagation, Freitas et al (2017) verified that the results were influenced by the origin of the plant material and by the substrate, with better responses for the seedlings production with the Barreiras material (CE) and with Tropstrato® substrate. Batista et al (2011) recommended the use of Plantmax® substrate for the production of pomegranate seedlings by cuttings.…”

The pomegranate (Punica granatum L.) presents potential for commercial exploitation as a fruit, ornamental or medicinal plant. However, for its usage in orchards, it is ideal that the seedlings come from vegetative propagation techniques. The aim of this work was to test the usage of indolebutyric acid (IBA) and substrates, at two harvesting times (before and after fruiting) in the cutting propagation of pomegranate. The work was carried out at UTFPR, Campus Dois Vizinhos. The experiments were installed in a randomized block design, in a 4 x 4 factorial scheme (IBA concentration x substrate), with four replications and ten cuttings per experimental unit. IAB was tested at concentrations 0; 1000; 2000 and 3000 mg L-1. The used substrates were Red Latosol, medium textured sand, commercial substrate MecPlant® and a mixture of Red Latosol + sand + commercial (1:1:1, v/v). The cuttings were placed in beds in a screened protected environment, with 50% shading. Irrigation was performed three times a day for 30 min., by a micro sprinkler. After 60 days, rooting (%), cuttings with callus (%), number of primary leaf and root shoots, length of the three largest roots and percentage of dead cuttings were evaluated. Cutting presented itself as a potential technique to be adopted for pomegranate, using sand, with the use of IBA at concentrations between 1600 and 1750 mg L-1. Cuttings must be collected before fruiting. However, rhizogenesis close to 50% was achieved at the time after such phenological stage.

“…Intrinsic factors include the genetic constitution of the plant, the endogenous level of inhibitors, cutting techniques, plant age and nutritional and water conditions of the parent plant (Cavalcante et al, 2019;Guimarães et al, 2019). Among the relevant extrinsic factors are the time of year of collection, use of growth regulators, substrate quality, and the environmental conditions (temperature, light and humidity) (Hartmann et al, 2011;Peralta et al, 2017;Freitas et al, 2017b;Marchi et al, 2018).…”

ABSTRACT The objective of this work was to evaluate the vegetative propagation of Hymenaea courbaril (jatobá) and Apuleia leiocarpa (garapa) using the mini-cutting technique with the use of indolebutyric acid (IBA) growth regulator in different types of mini-cuttings. Two experiments were set up: the first involving the two species and three mini-cutting techniques (basal, intermediate and apical) in the presence and absence of IBA (4000 mg kg-1). In the second experiment, only the garapa species was evaluated by testing the same three mini-cutting techniques at four IBA concentrations: 0, 1000, 2000 and 4000 mg kg-1. The mini-cuttings were obtained from 6-month-old seedlings produced from seeds in a nursery. A randomized block design was used in a 3 x 2 x 3 factorial scheme (three mini-cutting techniques, two IBA concentration levels and three evaluation dates) in the first experiment, and a 3 x 4 x 3 factorial scheme (three mini-cutting techniques, four IBA concentrations and three evaluation dates) in the second experiment. At 90 days, jatobá had an average survival of 54%, with less than 5% of total rooting, without significant influence of the mini-cutting technique or IBA use. Garapa presented higher survival for the basal mini-cuttings in both experiments, which were the only ones that took root. IBA did not influence survival or rooting percentage of garapa mini-cuttings, but negatively influenced the root number, length and dry mass. We concluded that the basal mini-cutting is a viable technique for vegetative propagation of garapa, presenting 40% of rooting, but the propagation by mini-cutting for jatobá was not successful under the conditions of this study.

Aiming to evaluate the effect of degumming methods and natural drying, as well as, the influence of different periods of seeds in quicklime solution on Punica granatum L. germination, were conducted two experiments. At first, the seeds from ripe fruits were subjected to the following sarcotesta extraction: natural fermentation at room temperature, during 72 hours; immersion in quicklime (CaO), during 24 hours; and non-degumming, taken as control. For the second experiment, the extraction method was carried out by the following mixture: seeds, quicklime, and distilled water; differing the immersion period (5, 10, 15, 20, and 25 hours). In both, the experimental design was completely randomized, performing the water content and germination test. The quicklime method is efficient to degrade and to eliminate the sarcotesta on P. granatum seeds, and the drying process provides a better germination. In addition, there is a linear increase on seed physiological quality when upgrades the immersion period in quicklime solution.
